I brought the Adidas Sennheiser headphones off Ebay for £45. Problem is they just don't fit in my ears at all, they seem to be pointing the wrong way. Outwards instead of facing my ears. I've never bought running headphones before and i know it should be simple but are they faulty or is it just how they sit? Its very uncomfortable and can't be right but they just won't fit any other way on me or my housemates.
